The estimation of total travel time on highway link for a day or year is the most important process for the feasibility analysis of highway or railway. Most of current guidelines for feasibility studies have been based on the time-traffic volume relationship from the BPR, and the traffic volumes have been determined by the application of the design hour factor to the annual average daily traffic volume. Both of the BPR function and the application of the design hour volume may result in the over-estimation of travel time due to the fact that the traffic volume on the large portion of highway links in Korea are close to the capacities. This study proposed a new way which is based on the distribution of hourly volumes for a year. It could be closer to the real situation, and provide more reasonable estimation. This methodology was validated for the national highways, but may be applicable for any type of highway with the AADT.

The purpose of this study was to examine whether gender collective self-esteem would moderate the relationship between perceived gender discrimination and belief in a just world (BJW) after controling the effect of personal self-esteem. For this, we measured perceived gender discrimination, personal self-esteem, gender collective self-esteem, and BJW in a sample of 300 women and conducted hierarchical regression analysis. The results revealed that, after controlling the effect of personal self-esteem, gender collective self-esteem moderated the association between perceived gender discrimination and BJW. That is, as gender collective self-esteem became greater, the negative effect of perceived gender discrimination on BJW decreased. In addition, we tested if four aspects of gender collective self-esteem (e.g. membership, private, public, identity) moderated the relationship between perceived gender discrimination and BJW. It was found that all of the four aspects except identity had significant moderating effects. Finally, we discussed limitations, suggestions for future research and clinical implications.

The Gyeongsang region experienced an epoch-making social transformation approximately around the second to first century BCE, including the replacement of Bronze Age types of tombs (such as dolmens, stone cist tombs, and earthen tombs with flat capstones) with clusters of wooden coffin tombs and the emergence of wajil pottery (soft stoneware) and ironware. These shifts in the archaeological material evidence have been discussed in the context of the formation of the states that comprised the three Han confederacies and in relation to wooden coffin tombs built in later periods. This paper explicates the appearance of clustered wooden coffin tombs with accompanying ironware by categorizing them. In particular, it examines the emergence of wooden coffin tombs by creating the Wolseong-dong type, which differs from Tomb No. 5 in Joyang-dong and Tomb No. 1 in Daho-ri with their deep burial pits and large quantities of prestige goods and soft stoneware items. The Wolseong-dong type of tomb commonly features ironware, including flat-bladed iron axes, oblong cast iron axes, iron wire, iron chisels, and iron swords; a small slender, rectangular wooden coffin tomb with a shallow burial pit of less than sixty centimeters; and pottery of a type preceding soft stoneware, such as long-necked jars, triangular attached-rim pottery bowls and pots, and mounted vessels. There are also a few bronzeware items found in them, but no prestige goods. This study scrutinizes tombs in Tamni-ri in Uiseong, Hagu-ri in Gyeongju, and Hakjeongdong in Daegu by comparing them with the Wolseong-dong type, and it confirms that in Sinseodong in Daegu, Wolseong-dong type tombs and later Joyang-dong type tombs have separate spatial distributions within the site. This also indicates that the Wolseong-dong type is a valid categorization among wooden coffin tombs. Although the rise of the Wolseong-dong type tomb is associated with the migration of a group, I reserve judgement on whether its origins should be understood in the context of the iron culture in the southwestern region of South Korea that was sparked by King Jun's advance to the south or if they lie in the western region of North Korea. Either way, the Wolseong-dong type is thought to be the tombs of a group of people with lower hierarchical status than the occupants of the later Joyang-dong type.

Leisure constraints mean the factor to constrain individual's leisure activity. Leisure constraints are composed of interpersonal constraints, interpersonal constraints and structural constraints. The purposes of this study are to show that intrapersonal leisure constraints have a strong effect on leisure preference, and leisure constraints are sequential and hierachical process. Intrapersonal constraints effect on leisure constraints in first step. And then interpersonal constraints and structural constraints effect on leisure participation. Those three leisure constraints are all linked together and come out step by step. Regarding adults as a population, who are more than 20-year-old and live in Seoul, 9 dongs were chose after dividing into upper and lower classes according to the value of their residence. The questionnaire consists of 4 parts: intrapersonal constraints, interpersonal constraints, structural constraints, and demographic characteristics. Results of this paper is that people who have strong intrapersonal constraints normally have problems caused from social structure. Intrapersonal constraints and structural constrains come out not seperately but together. Then, it can be said that structural constraints have an influence over intrapersonal constraints. So, it's necessary to solve structural problems to increase preferences and participations of them.

Mathematical curriculum has been developed based on learners' level and difficulties of contents. Succeed in solving problem in mathematics depends on the completion of the precedent learning. Thus, it is important to diagnose students beforehand. It is also important to develop problem-solving skills for students. In this thesis, Q&A system is proposed to help students learn various problem solving skills in mathematics. Although the system is currently applicable to mathematics, it can be applied to any other subjects.

This paper explored the marriage migrant mothers' experiences of parenting bi-ethnic children in South Korea based on the concepts of ethnic socialization and intersectionality. We analyzed in-depth interviews of 22 marriage migrant women from Vietnam residing in the capital region of South Korea. They had at least one child whose biological father is Korean. Children were 5 years old or older, attending preschool or elementary school. Five types of bi-ethnic socialization strategies were identified, which provide portraits of different situations in which marriage migrant women were placed. The five strategies that emerged from the data were 1) "Natural practice of bi-ethnic socialization" including two heterogeneous groups, "Coexistence of two cultures" and "Mixture of two cultures", 2) "Active practice of bi-ethnic socialization", 3) "Struggling practice of bi-ethnic socialization", 4) "Silence on bi-ethnic socialization", and 5) "Suppressed bi-ethnic socialization". The strategies of bi-ethnic socialization that marriage migrant women chose to raise their children reflected personal perceptions of Korean society and individual ethnic identity formed within Korean society. This study complements existing research on ethnic socialization by examining how ethnic socialization practices are shaped by multiple contexts marriage migrant women embedded in Korean society.

This study surveys the degree of residents' satisfaction on the current street space to suggest alternatives for the improvement of the street space design in detached house areas. In the results of the survey, we find the following. First, in the result of analysis on age, residential term, having children or not, income level, and type of house ownership, residents are homogeneous in social and economic characteristics. There are similarity in geographical, locational conditions, neighboring facilities, deterioration of residential house, and the time of residential formation among residential areas. Second, satisfactory determinants of residents on street space according to street types, are maintenance, protection of privacy, and parking space. Third, satisfactory determinants of residents on street hierarchy is the inner circulation road while unsatisfactory one is the inner roads. Fourth, age, residential term and type of house ownership are significant factors influencing residents' satisfaction. Factors influencing satisfaction on street space are also affecting total satisfaction and factors associated with street environment are perceived more important ones than factors associated with street activities. Thus we find the degrees of satisfaction for residents on street type and street hierarchy are different despite that general characteristics of residents are similar. We also find residents consider street noise and maintenance as critical factor among physical factors of street space.

본고의 목적은 헤테로크로닉을 통해 1980년대 노동시의 정치성에 대한 해석을 달리하고자 함에 있다. 1980년대 노동시에 대한 지금까지의 평가나 해석이 주로 맑스주의에 기반한 사회주의 리얼리즘 차원의 것이었다면, 이 논문에서는 조금 다른 각도에서 80년대 노동시의 정치성에 대해 살펴보고자 한다. 랑시에르의 헤테로크로닉 개념을 바탕으로 1980년대 대표적인 노동시인인 박영근, 백무산, 박노해의 노동시를 살펴볼 것인 바, 이들 세 시인의 1980년대 노동시에는 랑시에르의 헤테로크로닉 개념에 비추어 살펴볼 수 있는 유의미한 양상들이 자리 잡고 있다. 이들의 노동시에는 장시간 노동과 열악한 노동조건, 저임금 등의 환경 속에서 벗어나고자 하는 열망과 저항이 여러 유형으로 나타난다. 이들 시에 나타난 '인간해방'과 '노동해방'은 이념과 계급투쟁, 혹은 전형성의 원리 및 사회주의 리얼리즘 차원에서 주로 언급되었지만, 본고에서는 1980년대 노동시에 나타난 노동해방과 계급해방에의 열망과 저항을 과거 사회주의 문학 이론에 입각하여 읽어내기보다는 '사회적 위계'의 해체와 새로운 구축이라는 시간성을 통해 달리 읽어보고, 당대의 노동시가 갖는 정치성의 지평에 대해 재고(再考)하는 계기를 갖고자 한다.
